"A natural history of cheating from selfish genes to lying politicians. Nature is rife with cheating. Possums play possum, feigning death to cheat predators. Crows cry wolf to scare off rivals. Amphibians and reptiles are inveterate impostors. Even genes and cells cheat. The Liars of Nature and the Nature of Liars explores the evolution of cheating in the natural world, revealing how dishonesty has given rise to wondrous diversity. Blending cutting-edge...

Combining images of living plant stages with computer simulations allows you to easily bridge the gap between the familiar plant and the micro-environment contained within it. Three dimensional animations take you in and around reproductive structures such as the sorus, sporangium, and antheridium and archegonium. You see dynamic events such as spore formation, spore release, prothallus formation, sperm release, fertilization and embryo growth..

Combining images of living plant stages with computer simulations allows you to easily bridge the gap between the familiar plant and the micro-environment contained within it. Computer animations take you inside a clump of moss plants to illustrate external structure. You are then transported inside the tips of male and female stems where gametangia (sex organs), sperm release, fertilization and embryo development are illustrated..

The Oedogoniales are remarkable filamentous green algae. Their method of cell elongation is unique, utilizing a donut-shaped ring of soft wall material which is stretched to form the new daughter cell. While Oedogonium is a simple filament, the related Bulbochaete and Oedocladium are branched and Bulbochaete differentiates long hair cells. The zoospore is large and multiflagellated. Sexual reproduction is oogamous and either "macrandrous" or "nannandrous."...

The Volvocales and Chlorococcales share a common ancestry from a cell type exemplified by Chlamydomonas. Using live cells, this video shows how simple evolutionary trends working on Chlamydomonad ancestors have generated diversity and complexity.. In Volvocalean evolution, unicellular ancestors became multicellular (e.g., Volvox) by daughter cells adhering after division. Concurrently, they evolved various advanced characters (e.g., differentiation...

Combining images of living plant stages with computer simulations allows you to easily bridge the gap between the familiar plant and the micro-environment contained within it. Three dimensional animations take you inside the flower to witness dynamic events such as pollination, gametophyte formation, fertilization, embryo formation and fruit formation are seen as spectacular computer simulations..

An inspiring and challenging 20 minute video for high school or university biology students. This video starts by emphasizing the central importance of cells in life, and that living cells can only arise from other living cells by cell division. After distinguishing mitosis (nuclear division) from cytokinesis (cell division), several animal cells are shown undergoing mitosis and a 3D animation shows how the mitotic spindle is assembled. Chromosomes...

Describes many of the animals that can be found at the edge of the sea or in the sea itself.

"Biology is undergoing a quiet but profound transformation. Several aspects of the standard picture of how life works-the idea of the genome as a blueprint, of genes as instructions for building an organism, of proteins as precisely tailored molecular machines, of cells as entities with fixed identities, and more-have been exposed as incomplete, misleading, or wrong. In How Life Works, Philip Ball explores the new biology, revealing life to be a far...

"What exactly is a living thing? What is it made of? Your Guide to Life on Earth starts with the very basics of life and provides bite-sized chunks of information to explain in an easy-to-understand way the science behind the mystery of life on Earth. Fantastic illustrations highlight the amazing facts of life as we know it, from bacteria to blue whales, from slime molds to sequoias, and everything in between."-- Provided by publisher. What are living...
